Application filed April 7,

To all 1071 am it may concern Beit known that I, LAURENCE A. PETER- SEN, a citizen of the United States, residing at Hanna, in the county of Carbon and State of WVyoming, have invented new and useful Iil'lPTOVEHlQDlZS in Silo Staging, of which the following is a. specification.

This invention relates toimprovements in silo staging and has particular reference to a staging adapted to be used during the construction ofa silo. 1

The. principal object of this invention is to produce a staging which may be employed in the erection of silos of different height and diameter;

Another object is to produce a staging which is extremely simple and one which may be erected by one man and without undue effort.

Another object is to produce a silo staging which may be conveniently transported from one place to another the same taking up but a minimum amount of space during transportation.

Other objects and advantages'will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Figure I is a side elevation of my staging,

Figure II is a top plan view on the line II-II of Figure I,

Figure III is a detail view of one of the spacer members,

Figure IV is a detail a. staging plank,

Figure V is a detail perspective view of one of the supporting members.

Figure VI is a fragmentary perspective view showing how the staging is assembled. In the construction of a silo, it is generally necessary to construct a wooden staging both inside and outside of the silo, the same being made out ofrough lumber which is useless after the construction work'has been completed, and is knocked down and destroyed. I propose to overcome this waste by employing a staging which may be built up as needed and one which will fit all sizes of silos. I accomplish this object by employing staging built up of units.

In the accompanying drawings wherein perspective view of 1922. Serial No. 550,555.

for the purpose of illustration is shown a preferred embodiment of my invention, the numerals 6, 7, 8 and 9 refer toupright supports preferably made f angle iron. These supports are shown in Figures I, II and V. The supports each rest upon the ground and are provided with base plates as shown at 11 and 12, and are formed at their upper ends withslots 13 and 14 as shown in Figure V. These uprights are secured one to the other as by cross braces 16 and 17, it being understood that there are tw of these braces extending between each of the four uprights.

The construction of these braces is best shown in Figure I where it will be noted that the same are each of laminated construction which allows them to be lengthened by removing fastening bolts 18 and 19 and replacing them in proper openings to provide for the expansion or contraction as desired. Tie members capable of longitudinal adjustment by being formed of two pieces in overlapping relation as clearly shown in Figure III are indicated by the numerals 21, 22, 23 and 24:. These tie members are provided as shown in Figures I and III, and are adapted to extend between the uprights and to assist in keeping the same properly spaced. By referring to Figure II, it will be noted that these tie members cross and extend beyond the outer margin of the uprights. This crossing is affected by slotting each cross tie as shown at 20. This is also shown in Figure I. The crossing of these tie members together with the square corners .of the uprights, forms a socket 26 which socket is adaptedto receive a pin 27 secured upon the lower extremity of the next above upright. In securing the second set of uprights upon the top of the first set,

uprights at a point substantially midway of their length. These brackets are adapted t receive a staging plank 29 thereon. The staging plank is removable therefrom and is held to the uprights by strap iron plates 31 as is best shown in Figures I and IV. These strap iron plates are adapted to pass over eye bolts 32 and a pin 33 is inserted to prevent accidental slippage. These staging planks are adapted to be moved upwardly as the S110 progresses in height. If the space .the construction of silos, and at the same time take up very little room during trans portation or storage.

It is to be understood that the form of my invention herewith shown and described is to be taken as a preferred example of the same, and that various changes in the shape, size and arrangement of parts may be resorted t without departing from the spirit of the invention or the scope of the subjoined claim.

mergers Having thus described my invention I cla1m:

In a stag1ng,-a plurality of uprights supports spaced apart one from the other, ex-

tensible cross braces secured between adjacent uprights, extensible tie members adapted to rest on said uprights and having their extremities extend beyond said uprights, said extremities being adapted to support staging planks and brackets mounted on said uprights at a point substantially midway of'theirlength, said tie members and said uprights eachbeing adapted to receive therebetween a depending pin, said .pin being secured upon an upright and adapted to rest upon the top of said first mentioned uprights, cross braces secured between said second mentioned uprights and said first mentioned uprights, substantially as and for the purpose described. a, i I

In testimony whereof I affix my signature.
